On this earlier flight details display, the selected passenger is going from Charlotte, NC to Miami, FL. Their first flight was on AKA from CLT to ATL. The rest of their itinerary was on LLL going from ATL-DFW and then DFW-MIA. Why the out of the way routing? Notice the passengers preference under the "LE" column... they had the lowest possible preference for the length of the trip. They just didn't care about how long it took when compared to things like the cost ("$") and comfort ("C").
